Question

The length of a rectangle is 4 units shorter than half the width. If the length of the rectangle is 18 units, which equation can be
used to find w, the width of the rectangle?

Answer 1

Answer:

equation to find w:

$18u=\frac{w}{2}-4u$

and the value of the width is:

$w=44u$

Step-by-step explanation:

Information that we have:

Length: $l=18u$

"The length of a rectangle is 4 units shorter than half the width"

--------------------------------------------------------------------------------------------

Representing the width with $w$, what the last sentence is telling us is the following:

$l=\frac{w}{2} -4u$

Substituting the value of the length $l=18u$

$18u=\frac{w}{2}-4u$

this is the equation we can use to find the width of the rectangle.

And solving for $w$ we get:

$18u+4u=\frac{w}{2}\\ \\22u=\frac{w}{2} \\\\22u*2=w\\44u=w$
